I have 2 10 gallon permanent tanks to set up and two temporary 5 gallon tanks set up until the 10 gallons finish cycling.

I've recently moved and I had to leave the furniture behind that they are currently sitting on.

My first question.. can the 5 gallons safely remain on the floor (carpeting) while the 10g cycle? I just hate to go buy furniture just to hold them a month..

Second question, what stands do you suggest for a 10g? I thought about getting one of those stackable double stands that hold 2 10g, but I'm concerned about stability. I do have two places to put the stands.. one is on the second floor but I assume with something as light as 10g (under 100lbs) that it should hold just fine on the second floor.. most people weigh more than that.

The 5gal should be fine on the floor, no other pets that can mess with it right? The only thing I would be concerned with walking into it forgetting it's there..I never liked the stalking stands because in most I've seen the bottom one is way too low for me and I don't want to have to bend to adjust anything or feed. The links you put are all nice stands.

I like them all, and a few I was looking at as well, I like the cabinetry, doors and shelves for putting all the aquaria supplies, I am using a TV stand, same concept, and just as sturdy..and I found one for cheap at a local Salvation army..if you have those options, I would try there first.
